The principal purpose of the LLC is to hold equity interests in operating subsidiaries and to manage and dispose of such equity interests.

1.07 Qualification in Other Jurisdictions

The Board shall cause the LLC to be qualified or registered under applicable laws of any jurisdiction in which the LLC transacts business and shall be authorized to execute, deliver and file any certificates and documents necessary to effect such qualification or registration including, without limitation, the appointment of agents for service of process in such jurisdictions.

1.08 Partnership Classification

It is the intention of the parties hereto that the LLC be treated as a partnership for federal income tax purposes as defined in Section 7701 of the Code. Except as provided in Section 12.04, neither the LLC nor any Member shall file any tax election, or knowingly take (or knowingly cause or permit any of its Affiliates to take) any other action, that is inconsistent with the treatment of the LLC as a partnership for federal income tax purposes.

Jeremy Bender (or such other person as shall be selected by the Board) is hereby designated as the “partnership representative” (the “Partnership Representative”) as provided in Code Section 6223(a) (as amended by the Bipartisan Budget Act of 2015 (“BBA”)). The Partnership Representative is specifically directed and authorized to take whatever steps he, she or it, in his, her or its sole discretion, deems necessary or desirable to perfect such designation including, without limitation, filing any forms or documents with the Internal Revenue Service and taking such other action as may from time to time be required under Treasury Regulations. The Board may, in its discretion, change the Partnership Representative at any time and from time to time. The Partnership Representative shall act at the direction of the Board. The Board shall determine whether the LLC (either on its own behalf or on behalf of the Members) will contest or continue to contest any tax deficiencies assessed or proposed to be assessed by the Internal Revenue Service or any other taxing authority. The Partnership Representative shall manage administrative tax proceedings conducted at the LLC level by the Internal Revenue Service with respect to LLC matters, and shall deal with the Internal Revenue Service on any audits that are subject to the partnership audit provisions of the BBA. Each Member agrees that such Member will not independently act with respect to tax audits or tax litigation of the LLC unless previously authorized to do so in writing by the Partnership Representative, which authorization may be withheld by the Partnership Representative, at the direction of the Board. Members shall be bound by the actions taken by the Partnership Representative in accordance with this section. The LLC shall use commercially reasonable efforts to minimize the likelihood that any Member would bear any material tax, interest or penalties as a result of any audit or proceeding that is attributable to another Member (other than a predecessor in interest). Expenses of administrative proceedings relating to the determination of LLC items at the LLC level undertaken by the Partnership Representative shall be LLC expenses. Without limiting the generality of the foregoing, at the direction of the Board, the Partnership Representative shall have the sole and exclusive authority to make any elections on behalf of the LLC permitted to be made pursuant to Section 754 or any other section of the Code or the regulations promulgated thereunder. In the event of an audit of the LLC that is subject to the partnership audit procedures enacted under Section 1101 of the BBA (the “BBA Procedures”), at the direction of the Board,

3

the Partnership Representative shall have the right to make any and all elections and to take any actions that are available to be made or taken by the Partnership Representative or the LLC under the BBA Procedures. If an election under Code Section 6226(a) (as amended by the BBA) is made, the LLC shall furnish to each Member for the year under audit a statement of the Member’s share of any adjustment set forth in the notice of final partnership adjustment, and each Member shall take such adjustment into account as required under Code Section 6226(b) (as amended by the BBA). The Partnership Representative shall, at the LLC’s expense, file or cause to be filed all tax returns of the LLC with the appropriate tax authorities.

(d) Action at Meeting. When a quorum is present, any matter before the meeting shall be decided by vote of the Members holding a majority (on an as-converted to Common Share basis) of the Capital Shares voting on such matter except where a larger vote or separate class vote is required by law or by this Agreement. The LLC shall not vote any of its own Shares.

(a) Common Shares. Unless otherwise required by the Act or this Agreement, on any matter presented to the Members for their action or consideration at any meeting of the Members (or written actions in lieu of meetings), the holders of outstanding Common Shares (each, a “Common Member”) are entitled to one vote for each Common Share owned by them of record according to the books of the LLC.

It shall be the duty of each Member to notify the LLC of its address or any change thereof.

2.07 Record Date

In such case only Members of record on such record date shall be so entitled notwithstanding any transfer of Shares on the books of the LLC after the record date. If no record date is fixed, (a) the record date for determining Members entitled to notice of or to vote at a meeting of Members shall be at the close of business on the day preceding the day on which notice is given, or, if notice is waived, at the close of business on the day preceding the day on which the meeting is held, (b) the record date for determining Members entitled to express consent to LLC action in writing without a meeting, when no prior action by the Board is necessary, shall be the day on which the first written consent is expressed and (c) the record date for determining Members for any other purpose shall be at the close of business on the day on which the Board adopts the resolution relating thereto.

Except as otherwise provided in the Act, no Member, solely in his, her or its capacity as a Member, shall be obligated personally for any debt, obligation or liability of the LLC or of any other Member, whether arising in contract, tort or otherwise except for the obligations that such Member has expressly agreed in writing to provide indemnity or has otherwise guaranteed any obligation of the LLC or any subsidiary of the LLC. No Member, solely in his, her or its capacity as a Member, shall have any duty to the LLC, any other Member or any other person under this Agreement, applicable law or otherwise except for the obligations that such Member has expressly agreed in writing to provide indemnity or has otherwise guaranteed any obligation of the LLC or any subsidiary of the LLC and except for the express obligations of such Member set forth in this

9

Agreement. To the fullest extent permitted by the Act, all fiduciary and other duties of each Member, solely in his, her or its capacity as a Member, to the LLC, any other Member or any other person under this Agreement, applicable law or otherwise, other than the obligations that such Member has expressly agreed in writing to provide indemnity or has otherwise guaranteed any obligation of the LLC or any subsidiary of the LLC and except for the express obligations of such Member set forth in this Agreement, are expressly eliminated and each party hereto hereby agrees that such elimination of such fiduciary and other duties is reasonable. Without limiting the generality of the foregoing, in the event that a Member who is not an employee of the LLC or any subsidiary of the LLC acquires knowledge of a potential transaction or matter that may be a business opportunity for such Member or an Affiliate of such Member, such Member shall not have a duty to communicate or offer such business opportunity to the LLC or be liable to the LLC or its Members or creditors or any other person for breach of any duty as a Member by reason of the fact that such Member pursues or acquires such business opportunity for such Member or an Affiliate, directs such business opportunity to another person, or does not communicate information regarding, or offer, such business opportunity to the LLC. No Member shall have any responsibility to restore any negative or deficit balance in its Capital Account (as defined in Section 8.01) or to contribute to or in respect of the liabilities or obligations of the LLC or to return distributions made by the LLC except as required by the Act or other applicable law. The failure of the LLC to observe any formalities or requirements relating to the exercise of its powers or the management of its business or affairs under this Agreement or the Act shall not be grounds for making its Members or the Managers responsible for the liabilities of the LLC. Except for (a) claims as to which such Member has agreed to provide indemnity or has otherwise guaranteed any obligation of the LLC or any subsidiary of the LLC, (b) the breach of the express obligations of such Member set forth in this Agreement and (c) willful misconduct or fraud by such Member, the LLC shall indemnify, to the fullest extent permitted by the Act as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the LLC to provide broader indemnification rights than the Act permitted the LLC to provide prior to such amendment) any Member who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (whether or not brought by or in the right of the LLC) by reason of the fact that he, she or it is or was a Member, solely in his, her or its capacity as a Member, from and against any claim by any person against such Member acting in his, her or its capacity as a Member for all expenses (including reasonable attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or it in connection with such action, suit or proceeding. The foregoing indemnification rights conferred on any Member by this Section 2.09 shall not be exclusive of any other rights which such Member may have or hereafter acquire under any statute, the Certificate of Formation, this Agreement, other agreement, vote of the Members or the Board or otherwise.

2.10 Authority

Unless expressly authorized by the Board after the date hereof, no Member, solely in his, her or its capacity as a Member, shall be an agent of the LLC or have any right, power or authority to act for or to bind the LLC or to undertake or assume any obligation or responsibility of the LLC or of any other Member.

10

2.11 No Right to Withdraw

No Member shall have any right to resign or withdraw from the LLC without the consent of the Board unless such Member elects to forfeit his, her or its Shares to the LLC in connection with such resignation and withdrawal; such resignation or withdrawal shall not entitle such Member to receive any distribution from the LLC (including a distribution for the fair value of such Member’s Shares) or the repayment of its Contribution. This Section 2.11 shall not affect the rights of a Member otherwise provided for in this Agreement to receive distributions in connection with an actual or deemed liquidation, dissolution or winding up of the LLC.

2.12 Rights to Information

Members shall have the right to receive from the Board, upon request, a copy of the Certificate of Formation and of this Agreement, as amended from time to time, and such other information regarding the LLC as is required by the Act, subject to reasonable conditions and standards established by the Board, as permitted by the Act, which may include, without limitation, withholding, or restrictions on the use and disclosure of, confidential information.

2.13 Tax Information

The LLC will prepare IRS Form 1065 and all income tax returns of the LLC for each year which are required to be filed and will cause such returns to be timely filed. Within ninety (90) days after the end of each fiscal year, the LLC will deliver to each person that was a Member at any time during such year such Member’s Schedule K-1 and such additional information in the LLC’s possession, if any, with respect to the LLC that is reasonably requested by such Member and is necessary for the preparation of such Member’s income tax returns and any tax refunds or exemptions from withholding.

2.14 Confidentiality

Each Member shall keep confidential and will not disclose, divulge, or use for any purpose (other than to monitor its investment in the LLC or to enforce its rights under this Agreement or any other agreement between the Company and the Members ) any confidential information obtained from the LLC or its subsidiaries pursuant to the terms of this Agreement (including notice of the LLC’s intention to file a registration statement), unless such confidential information (a) is known or becomes known to the public in general (other than as a result of a breach of this Section 2.14 by such Member), (b) is or has been independently developed or conceived by such Member without use of the LLC’s confidential information or (c) is or has been made known or disclosed to such Member by a third party without a breach of any obligation of confidentiality such third party may have to the LLC; provided, however, that a Member may disclose confidential information (i) to his, her or its attorneys, accountants, consultants, investment managers and other professionals to the extent necessary to obtain their services in connection with monitoring his, her or its investment in the LLC or to enforce its rights under this Agreement or any other agreement between the Company and the Members; (ii) to any prospective purchaser of Shares from such Member, if such prospective purchaser is subject to a confidentiality agreement with such Member or is otherwise bound to keep such information confidential by obligations at least as restrictive as the provisions of this Section

11

2.14 and provided that such prospective purchase is a Competitor (as defined in the Rights Agreement) of the LLC; (iii) to any regulator, existing or prospective Affiliate, partner, member, stockholder, beneficial owner or wholly owned subsidiary of such Member in the ordinary course of business, provided that, to the extent permitted by applicable law, such Member informs such person that such information is confidential and directs such person to maintain the confidentiality of such information; or (iv) as may otherwise be required by law, regulation, rule, court order or subpoena, provided that, to the extent permitted by applicable law, such Member promptly notifies the LLC of such disclosure and takes reasonable steps to minimize the extent of any such required disclosure. Each party acknowledges that monetary damages calculated at law would not be an adequate remedy for breach of this Section 2.14, and that each party shall be entitled to seek injunctive relief, including injunction and specific performance, or other more appropriate equitable relief (in addition to any other remedy it may have under this Agreement or otherwise at law or in equity) in the event of any breach of this Section 2.14 by the other party.

2.15 Lock-Up Obligation.

Each Member will not, without the prior written consent of the LLC and managing underwriter, during the period commencing on the date of the final prospectus relating to the registration by the LLC for its own behalf of its Common Shares or any other equity securities under the Securities Act and ending on the date specified by the LLC and the managing underwriter (such period not to exceed 180 days): (a) lend; offer; pledge; sell; contract to sell; sell any option or contract to purchase; purchase any option or contract to sell; grant any option, right, or warrant to purchase; or otherwise transfer or dispose of, directly or indirectly, any Common Shares or any securities convertible into or exercisable or exchangeable (directly or indirectly) for Common Shares or (b) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (a) above is to be settled by delivery of Common Shares or other securities, in cash or otherwise. The foregoing provisions of this Section 2.15: (i) shall apply only to the initial underwritten public offering of Common Shares; (ii) shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement; (iii) shall not apply to the sale of any Shares acquired by the Member following the effectiveness of the registration statement for the initial public offering; (iv) shall not apply to any transfers by a Member that is a corporation, partnership, limited liability company or other business entity, provided that (x) such transfer is to another corporation, partnership, limited liability company or other business entity that controls, is controlled by or is under common control with such Member or as part of a disposition, transfer or distribution without consideration by the undersigned to its equity holders, limited partners or members, (y) no filing under the Exchange Act or other public announcement, reporting an overall reduction in beneficial ownership of Common Shares or any security convertible into or exercisable or exchangeable for Common Shares collectively held by such transferring Member, its Affiliates, or its or their beneficial owners, equity holders, limited partners and/or members, shall be required or shall be voluntarily made during the lock up period (provided, however, that the transferring Member shall be permitted to make required filings on a Schedule 13D, Form 13F, or Schedule 13G under the Exchange Act; and provided further that any filing under the Exchange Act or other public announcement shall include a footnote noting the circumstances described in this clause) and (z) the transferee agrees, in writing, to be bound by the restrictions set forth herein; and (v) shall be applicable to the Members only if all officers and Managers of

12

the LLC are subject to the same restrictions and the LLC uses commercially reasonable efforts to obtain a similar agreement from all members individually owning more than one percent (1%) of the LLC’s then-outstanding Common Shares. The underwriters in connection with such registration are intended third-party beneficiaries of this Section 2.15 and shall have the right, power, and authority to enforce the provisions hereof as though they were a party hereto. Each Member further agrees to execute such agreement as may be reasonably requested by the underwriters in connection with such registration that are consistent with this Section 2.15 or that are necessary to give further effect thereto; provided that in the event of any conflict or inconsistency between the terms of such separate agreement and this Section 2.15, including, without limitation, any provisions regarding permitted transfers in such separate agreement, the terms of such separate agreement shall control. Any discretionary waiver or termination of the restrictions of any or all of such agreements by the LLC or the underwriters shall apply pro rata to all Members subject to such agreements, based on the number of shares subject to such agreements. The LLC may impose stop-transfer instructions with respect to the securities subject to the foregoing restriction until the end of the lock-up period.

ARTICLE III. Capital Structure

3.01 Classes of Shares

(a) Authorized Shares. Interests of Members in the profits and losses of the LLC and the right of Members to distributions and allocations and a return of capital contributions and other amounts specified herein shall be evidenced by shares of limited liability company interests in the LLC. Initially, there shall be three classes of Shares designated as “Common Shares”, “Preferred Shares” and “Incentive Shares”. The term “Shares” shall mean, collectively, the Common Shares, the Preferred Shares and the Incentive Shares. The LLC has authority to issue (i) 17,000,000 Common Shares, (ii) 13,973,939 Preferred Shares, 9,828,498 of which shall be designated “Series A Convertible Preferred Shares” and 4,145,441 of which shall be designated “Series B Convertible Preferred Shares” and (iii) 3,838,356 Incentive Shares. The Shares owned by the Members as of the date hereof are set forth on Schedule A.

(b) Incentive Shares. The Incentive Shares shall have the rights and powers set forth in this Section 3.01(b).

(i) The Board shall have the right to issue Incentive Shares to managers, directors, officers, employees, advisors and consultants of the LLC and its subsidiaries (the “Incentive Members”) pursuant to the LLC’s Incentive Share Plan (as amended from time to time, the “Incentive Plan”) and an Award Agreement entered into by the LLC with such Incentive Member (each, as amended from time to time, an “Award Agreement”). The terms of each Award Agreement shall specify the number of Incentive Shares issued to the applicable Incentive Member. The Board shall have the power and discretion to approve which managers, directors, officers, employees, advisors and consultants of the LLC and its subsidiaries shall be offered and issued such Incentive Shares, the number of Incentive Shares to be offered and issued to each such person, the vesting, forfeiture and other restrictions, if any, governing such Incentive Shares, the purchase price therefor, if any, and any such other terms and conditions as it shall deem appropriate. In connection with any approved issuance to any Incentive Member of Incentive Shares hereunder, such Incentive Member shall execute a counterpart to this Agreement, or

13

otherwise be deemed to have become a party to this Agreement by executing an Award Agreement, accepting and agreeing to be bound by all terms and conditions hereof, and shall enter into such other documents and instruments to effect such issuance (including, without limitation, an Award Agreement) as are required by the Board. Notwithstanding anything to the contrary in this Agreement, except as required by applicable law, no Incentive Member shall be entitled to any voting, consent or approval rights with respect to the Incentive Shares held by such Incentive Member. Each Incentive Member shall be a Member hereunder unless and until such Incentive Member does not hold any Shares (including, without limitation, as a result of the forfeiture of all of the Incentive Shares held by such Incentive Member).

(ii) Unless otherwise approved by the Board, all Incentive Shares shall vest over a four (4) year period, with the first twenty-five percent (25%) of such Incentive Shares vesting following twelve (12) months of continued employment or service, and the remaining Incentive Shares vesting in equal monthly installments over the following thirty-six (36) months. Subject to the preceding sentence, each Incentive Member’s Incentive Shares shall vest as set forth in the Incentive Plan and the applicable Award Agreement for such Incentive Shares. “Unvested Incentive Shares” means any Incentive Shares that have not vested as of the date of determination pursuant to the Incentive Plan and the applicable Award Agreement. “Vested Incentive Shares” means any Incentive Shares that have vested as of the date of determination pursuant to the Incentive Plan and the applicable Award Agreement.

(iii) If an Incentive Member’s Continuous Service (as such term is defined in the Incentive Plan) is terminated for any reason, then, unless otherwise set forth in the Award Agreement for any Incentive Member, all of the Unvested Incentive Shares held by such Incentive Member shall immediately be forfeited and revert back to the LLC without any payment to the Incentive Member.

(iv) The LLC and each Member agree to treat each Incentive Member’s Incentive Shares (such interest, a “Profits Interest”) as a separate “Profits Interest” within the meaning of Rev. Proc. 93-27, 1993-2 C.B. 343, and it is the intention of the Members that distributions to each Incentive Member pursuant to Article X be limited to the extent necessary so that the Profits Interest of such Incentive Member qualifies as a “Profits Interest” under Rev. Proc. 93-27, and this Agreement shall be interpreted accordingly. In accordance with Rev. Proc. 2001- 43, 2001-2 C.B. 191, the LLC shall treat a Member holding an Incentive Share as the owner of such Incentive Share from the date it is granted, and shall file its IRS Form 1065, and issue appropriate Schedule K-1s to such Member, allocating to such Member its distributive share of all items of income, gain, loss, deduction and credit associated with such Profits Interest as if it were a fully Vested Incentive Share. Each Incentive Member agrees to take into account such distributive share in computing its income tax liability for the entire period during which it holds the Profits Interest. The LLC and each Member agree not to claim a deduction (as wages, compensation or otherwise) for the fair market value, as determined in good faith by the Board, of such Profits Interest issued to an Incentive Member, either at the time of grant of the Profits Interest or at the time the Profits Interest becomes substantially vested. The undertakings contained in this Section 3.01(b) shall be construed in accordance with Section 4 of Rev. Proc. 2001-43. Each Incentive Member shall be required to file an election pursuant to Section 83(b) of the Code (a “Section 83(b) Election”) with respect to its Incentive Shares no later than ten days after receipt of such Incentive Shares. The provisions of this Section 3.01(b) shall apply regardless of whether or not an Incentive Member files a Section 83(b) Election with respect to its Incentive Shares.

14

(v) As of the date of each grant of Incentive Shares to an Incentive Member, the Board shall establish an initial “Participation Threshold” amount with respect to each such Incentive Share granted on such date. Unless otherwise determined by the Board, the Participation Threshold with respect to an Incentive Share shall be equal to or greater than the amount that would be distributed with respect to all Shares pursuant to Section 10.04(b) in a hypothetical transaction in which the LLC sold all of its assets for fair market value (as determined in good faith by the Board, which determination shall take into account any factors and using any valuation methodologies that the Board in good faith deems relevant in its sole discretion, including potentially using independent appraisers, industry comparables, internal valuations and any other customary valuation measures), discharged in full all of its outstanding liabilities and distributed the remaining proceeds therefrom in liquidation of the LLC pursuant to Section 10.04(b) (as determined immediately prior to the issuance of such Incentive Share, such that in such hypothetical liquidation of the LLC, no amount would be available for distribution in respect of such Incentive Share as of the issuance of such Incentive Share).

(vi) The Board is hereby authorized and directed to cause the LLC to make an election to value any Shares issued by the LLC as compensation for services to the LLC (collectively, “Compensatory Interests”) at liquidation value (the “Safe Harbor Election”), as the same may be permitted pursuant to or in accordance with the finally promulgated successor rules to Proposed Regulations Section 1.83-3(l) and IRS Notice 2005-43 (collectively, the “Proposed Rules”). The Board shall cause the LLC to make any allocations of items of income, gain, deduction, loss or credit (including forfeiture allocations and elections as to allocation periods) necessary or appropriate to effectuate and maintain the Safe Harbor Election.

(vii) Any such Safe Harbor Election shall be binding on the LLC and on all of its Members with respect to all permitted transfers of Compensatory Interests thereafter made by the LLC while a Safe Harbor Election is in effect. A Safe Harbor Election once made may be revoked by the Board as permitted by the Proposed Rules or any applicable rule.

(viii) Each Member (including any person to whom a Compensatory Interest is transferred in connection with the performance of services), by signing this Agreement or by accepting such transfer, hereby agrees to comply with all requirements of the Safe Harbor Election with respect to all Compensatory Interests transferred while the Safe Harbor Election remains effective.

(ix) The Board shall file or cause the LLC to file all returns, reports and other documentation as may be required to perfect and maintain the Safe Harbor Election with respect to transfers of Compensatory Interests covered by such Safe Harbor Election.

(x) Notwithstanding anything to the contrary in this Agreement (including, without limitation, Section 13.05), the Board is hereby authorized and empowered, without further vote or action of the Members, to amend this Agreement as necessary to comply with the Proposed Rules or any similar rule, in order to provide for a Safe Harbor Election and the ability to maintain or revoke the same, and shall have the authority to execute any such amendment

15

by and on behalf of each Member; provided that such amendment may be made by the Board only to the extent such amendment will not have a material effect on the amounts distributed to any Member pursuant to Section 10.04 hereof upon liquidation or dissolution of the LLC, and the Board shall use its reasonable best efforts to effect as little change in the tax arrangements among the Members as the Board shall determine in its reasonable discretion to be necessary to comply with such Safe Harbor Election. Any undertakings by the Board necessary to enable or preserve a Safe Harbor Election may be reflected in such amendments and to the extent so reflected shall be binding on each Member. Each Member agrees to cooperate with the Board to perfect and maintain any Safe Harbor Election, and to timely execute and deliver any documentation with respect thereto reasonably requested by the Board.

(xi) Without limitation of any other provision herein, no transfer of any Profits Interest in the LLC by a Member, to the extent permitted by this Agreement, shall be effective unless prior to such transfer, the transferee, assignee or intended recipient of such Profits Interest shall have agreed in writing to be bound by the provisions of this Section 3.01(b), in form satisfactory to the Board.

(xii) This Section 3.01(b) together with the Award Agreements pursuant to which the Incentive Shares are issued are intended to qualify as a compensatory benefit plan within the meaning of Rule 701 of the Securities Act (and any similarly applicable state “blue sky” securities laws) and the issuance of Incentive Shares pursuant hereto is intended to qualify for the exemption from registration under the Securities Act provided by Rule 701 (and any similarly applicable state “blue sky” securities laws); provided, that the foregoing shall not restrict or limit the LLC’s ability to issue any Incentive Shares pursuant to any other exemption from registration under the Securities Act available to the LLC. The LLC may make the Incentive Shares and any issuance thereof and any applicable Award Agreements subject to the terms and conditions of any other equity incentive plan consistent with the terms of this Agreement, as may have been adopted by the LLC.

(c) Subject to compliance with the terms of this Agreement and the Rights Agreement, the LLC may from time to time issue additional Shares to existing Members or new Members and may amend this Agreement to designate additional classes of Shares having different relative rights, powers and preferences including, without limitation, rights and powers that are superior and/or prior to those of existing classes of Shares, or the right to vote as a separate class or group on specified matters.

3.02 Conversion of Preferred Shares

(a) Voluntary Conversion. Each Preferred Share shall be convertible, at the option of the holder thereof, at any time and from time to time after the date of issuance of such Preferred Share and without the payment of additional consideration by the holder thereof, into such number of Common Shares as is determined by dividing the Original Issue Price (as defined below) by the Conversion Price (as defined below) in effect at the time of conversion. The “Original Issue Price” shall mean $6.7401 per share for each Series A Convertible Preferred Share (as adjusted for any combinations, splits, recapitalizations and similar events with respect to the Series A Convertible Preferred Shares), and $31.3597 per share for each Series B Convertible Preferred Share (as adjusted for any combinations, splits, recapitalizations and similar events with

16

respect to the Series B Convertible Preferred Shares). The “Conversion Price” for each Series A Convertible Preferred Share and Series B Convertible Preferred Share shall initially mean the respective Original Issue Price for such applicable Preferred Share. Such initial Conversion Price, and the rate at which Preferred Shares may be converted into Common Shares, shall be subject to adjustment as set forth herein. To exercise its conversion privilege, a Preferred Member shall give written notice to the LLC that such Preferred Member elects to convert such Preferred Shares. Such notice shall also state the name or names (with address or addresses) in which the Common Shares issuable upon such conversion shall be issued; provided, that if any name or names in which such Common Shares are to be issued reflect a Transfer of such Preferred Shares, such Transfer and issuance shall be subject to the provisions of Article XI hereof. The date the LLC receives such written notice, together with assignment, if required, shall be the “Conversion Date”. Such conversion shall be deemed to have been effected immediately prior to the close of business on the Conversion Date and the Board shall amend Schedule A to reflect such conversion.

(b) Fractional Shares. No fractional Common Share shall be issued upon conversion of the Preferred Shares. In lieu of any fractional shares to which the holder would otherwise be entitled, the LLC shall pay cash equal to such fraction multiplied by the fair market value of a Common Share as determined in good faith by the Board. Whether or not fractional shares would be issuable upon such conversion shall be determined on the basis of the total number of Preferred Shares the holder is at the time converting into Common Shares and the aggregate number of Common Shares issuable upon such conversion.

(c) Reservation of Shares. The LLC shall at all times when the Preferred Shares shall be outstanding, reserve and keep available out of its authorized but unissued Common Shares, for the purpose of effecting the conversion of the Preferred Shares, such number of its duly authorized Common Shares as shall from time to time be sufficient to effect the conversion of all outstanding Preferred Shares; and if at any time the number of authorized but unissued Common Shares shall not be sufficient to effect the conversion of all then outstanding Preferred Shares, then the LLC and the Members shall take such action as may be necessary to increase its authorized but unissued Common Shares to such number as shall be sufficient for such purposes.

(d) Effect of Conversion. All Preferred Shares which shall have been converted as herein provided shall no longer be deemed to be outstanding and all rights with respect to such shares shall immediately cease and terminate on the Conversion Date, except only the right of the holders thereof to receive Common Shares in exchange therefor, to receive payment in lieu of any fraction of a share otherwise issuable upon such conversion as provided in Section 3.02(b) and to receive payment of any distributions that are declared but unpaid thereon. Any Preferred Shares so converted shall be retired and cancelled and may not be reissued, and the LLC may thereafter take such appropriate action as may be necessary to reduce the authorized number of Preferred Shares accordingly.

(e) Taxes. The LLC shall pay any and all issue and other similar taxes that may be payable in respect of any issuance or delivery of Common Shares upon conversion of Preferred Shares pursuant to this Section 3.02. The LLC shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of Common Shares in a name other than that in which Preferred Shares so converted were registered, and no such issuance or delivery shall be made unless and until the person or entity requesting such issuance has paid to the LLC the amount of any such tax or has established, to the satisfaction of the LLC, that such tax has been paid.

17

3.03 Adjustments to Conversion Price for Diluting Issues

(a) Special Definitions. For purposes of this Article III, the following definitions shall apply:

(i) “Option” shall mean rights, options or warrants to subscribe for, purchase or otherwise acquire Common Shares, Incentive Shares or Convertible Securities.

(ii) “Series B Original Issue Date” shall mean the date on which the first Series B Convertible Preferred Share was issued.

(iii) “Convertible Securities” shall mean any evidences of indebtedness, shares or other securities directly or indirectly convertible into or exchangeable for Common Shares or Incentive Shares, but excluding Options.

(iv) “Additional Shares” shall mean all Common Shares or Incentive Shares issued (or, pursuant to Section 3.03(c) below, deemed to be issued) by the LLC after the Series B Original Issue Date, other than the following (collectively, “Exempted Securities”):

(1) Shares issued pursuant to the Purchase Agreement;

(2) Common Shares, Options or Convertible Securities issued as a distribution on Preferred Shares;

(3) Common Shares, Options or Convertible Securities issued by reason of a share split, split-up or other distribution on Common Shares that is covered by Section 3.04, 3.05, or 3.06;

(4) Incentive Shares issued to employees or directors of, or consultants or advisors to, the LLC or any of its subsidiaries pursuant to this Agreement and the Incentive Plan or any other equity incentive plan approved by the Board, which approval must include the affirmative vote, consent or approval of at least two of the Preferred Managers;

(5) Common Shares or Convertible Securities actually issued upon the exercise of Options or Common Shares actually issued upon the conversion or exchange of Convertible Securities, in each case provided such issuance is pursuant to the terms of such Option or Convertible Security;

(6) Common Shares, Options or Convertible Securities issued to banks, equipment lessors or other financial institutions, or to real property lessors, pursuant to a debt financing, equipment leasing or real property leasing transaction approved by the Board;

18

(8) Common Shares, Options or Convertible Securities issued as acquisition consideration pursuant to the acquisition of another entity by the LLC by merger, purchase of substantially all of the assets or other reorganization or to a joint venture agreement, provided that such issuances are approved by the Board, including approval of at least two of the Preferred Managers; or

(9) Common Shares, Options or Convertible Securities issued in connection with sponsored research, collaboration, technology license, development, OEM, marketing or other similar agreements or strategic partnerships approved by the Board.

(b) No Adjustment of Conversion Price. No adjustment in the Conversion Price of a given series of Preferred Shares shall be made as the result of the issuance or deemed issuance of Additional Shares if the LLC receives written notice from holders of a majority of Preferred Shares of such series agreeing that no such adjustment shall be made in respect of the Conversion Price of such series of Preferred Shares as the result of the issuance or deemed issuance of such Additional Shares.

(c) Deemed Issue of Additional Shares.

(i) If the LLC at any time or from time to time after the Series B Original Issue Date shall issue any Options or Convertible Securities (excluding Options or Convertible Securities which are themselves Exempted Securities) or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities, then the maximum number of Common Shares or Incentive Shares (as set forth in the instrument relating thereto, assuming the satisfaction of any conditions to exercisability, convertibility or exchangeability but without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares issued as of the time of such issue or, in case such a record date shall have been fixed, as of the close of business on such record date.

(ii) If the terms of any Option or Convertible Security, the issuance of which resulted in an adjustment to the Conversion Price pursuant to the terms of Section 3.03(d), are revised as a result of an amendment to such terms or any other adjustment pursuant to the provisions of such Option or Convertible Security (but excluding automatic adjustments to such terms pursuant to anti-dilution or similar provisions of such Option or Convertible Security) to provide for either (1) any increase or decrease in the number of Common Shares or Incentive Shares issuable upon the exercise, conversion and/or exchange of any such Option or Convertible Security or (2) any increase or decrease in the consideration payable to the LLC upon such exercise, conversion and/or exchange, then, effective upon such increase or decrease becoming effective, the Conversion Price computed upon the original issue of such Option or Convertible Security (or upon the occurrence of a record date with respect thereto) shall be readjusted to such Conversion Price as would have been obtained had such revised terms been in effect upon the original date of issuance of such Option or Convertible Security. Notwithstanding the foregoing, no readjustment pursuant to this clause (ii) shall have the effect of increasing the Conversion Price to an amount which exceeds the lower of (A) the Conversion Price in effect immediately prior to the original adjustment made as a result of the issuance of such Option or Convertible Security, or (B) the Conversion Price that would have resulted from any issuances of Additional Shares (other than deemed issuances of Additional Shares as a result of the issuance of such Option or Convertible Security) between the original adjustment date and such readjustment date.

19

(iii) If the terms of any Option or Convertible Security (excluding Options or Convertible Securities which are themselves Exempted Securities), the issuance of which did not result in an adjustment to the Conversion Price pursuant to the terms of Section 3.03(d) (either because the consideration per share (determined pursuant to Section 3.03(e)) of the Additional Shares subject thereto was equal to or greater than the Conversion Price then in effect, or because such Option or Convertible Security was issued before the Series B Original Issue Date), are revised after the Series B Original Issue Date as a result of an amendment to such terms or any other adjustment pursuant to the provisions of such Option or Convertible Security (but excluding automatic adjustments to such terms pursuant to anti-dilution or similar provisions of such Option or Convertible Security) to provide for either (1) any increase in the number of Common Shares or Incentive Shares issuable upon the exercise, conversion or exchange of any such Option or Convertible Security or (2) any decrease in the consideration payable to the LLC upon such exercise, conversion or exchange, then such Option or Convertible Security, as so amended or adjusted, and the Additional Shares subject thereto (determined in the manner provided in Section 3.03(c)(i)) shall be deemed to have been issued effective upon such increase or decrease becoming effective.

(iv) Upon the expiration or termination of any unexercised Option or unconverted or unexchanged Convertible Security (or portion thereof) which resulted (either upon its original issuance or upon a revision of its terms) in an adjustment to the Conversion Price pursuant to the terms of Section 3.03(d), the Conversion Price shall be readjusted to such Conversion Price as would have been obtained had such Option or Convertible Security (or portion thereof) never been issued.

(v) If the number of Common Shares or Incentive Shares issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or the consideration payable to the LLC upon such exercise, conversion and/or exchange, is calculable at the time such Option or Convertible Security is issued or amended but is subject to adjustment based upon subsequent events, any adjustment to the Conversion Price provided for in this Section 3.03(c) shall be effected at the time of such issuance or amendment based on such number of shares or amount of consideration without regard to any provisions for subsequent adjustments (and any subsequent adjustments shall be treated as provided in clauses (ii) and (iii) of this Section). If the number of Common Shares or Incentive Shares issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or the consideration payable to the LLC upon such exercise, conversion and/or exchange, cannot be calculated at all at the time such Option or Convertible Security is issued or amended, any adjustment to the Conversion Price that would result under the terms of this Section 3.03(c) at the time of such issuance or amendment shall instead be effected at the time such number of shares and/or amount of consideration is first calculable (even if subject to subsequent adjustments), assuming for purposes of calculating such adjustment to the Conversion Price that such issuance or amendment took place at the time such calculation can first be made.

20

(d) Adjustment of Conversion Price Upon Issuance of Additional Shares. In the event the LLC shall at any time after the Series B Original Issue Date issue Additional Shares (including Additional Shares deemed to be issued pursuant to Section 3.03(c)), without consideration or for a consideration per share less than the Conversion Price in effect immediately prior to such issuance or deemed issuance, then the Conversion Price shall be reduced, concurrently with such issue, to a price (calculated to the nearest one-hundredth of a cent) determined in accordance with the following formula:

CP₂ = CP₁* (A + B) ÷ (A + C).

For purposes of the foregoing formula, the following definitions shall apply:

(i) “CP₂” shall mean the Conversion Price in effect immediately after such issuance or deemed issuance of Additional Shares;

(ii) “CP₁” shall mean the Conversion Price in effect immediately prior to such issuance or deemed issuance of Additional Shares;

(iii) “A” shall mean the number of Common Shares and Incentive Shares outstanding immediately prior to such issuance or deemed issuance of Additional Shares (treating for this purpose as outstanding all Common Shares and Incentive Shares issuable upon exercise of Options outstanding immediately prior to such issuance or deemed issuance or upon conversion or exchange of Convertible Securities (including the Preferred Shares) outstanding (assuming exercise of any outstanding Options therefor) immediately prior to such issue);

(iv) “B” shall mean the number of Common Shares or Incentive Shares that would have been issued if such Additional Shares had been issued or deemed issued at a price per share equal to CP1 (determined by dividing the aggregate consideration received by the LLC in respect of such issue by CP1); and

(v) “C” shall mean the number of such Additional Shares issued in such transaction.

(e) Determination of Consideration. For purposes of this Section 3.03, the

consideration received by the LLC for the issuance or deemed issuance of any Additional Shares shall be computed as follows:

(i) Cash and Property: Such consideration shall:

(1) insofar as it consists of cash, be computed at the aggregate amount of cash received by the LLC, excluding amounts paid or payable for accrued interest;

(2) insofar as it consists of property other than cash, be computed at the fair market value thereof at the time of such issue, as determined in good faith by the Board; and

(3) in the event Additional Shares are issued together with other shares or securities or other assets of the LLC for consideration which covers both, be the proportion of such consideration so received, computed as provided in clauses (1) and (2) above, as determined in good faith by the Board.

21

(ii) Options and Convertible Securities. The consideration per share received by the LLC for Additional Shares deemed to have been issued pursuant to Section 3.03(c), relating to Options and Convertible Securities, shall be determined by dividing:

(1) the total amount, if any, received or receivable by the LLC as consideration for the issue of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the LLC upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities, by

(2) the maximum number of Common Shares or Incentive Shares (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities.

3.04 Adjustment for Share Splits and Combinations

If the LLC shall at any time or from time to time after the Series B Original Issue Date effect a subdivision of the outstanding Common Shares, the Conversion Price in effect immediately before that subdivision shall be proportionately decreased so that the number of Common Shares issuable on conversion of each Preferred Share shall be increased in proportion to such increase in the aggregate number of Common Shares outstanding. If the LLC shall at any time or from time to time after the Series B Original Issue Date combine the outstanding Common Shares, the Conversion Price in effect immediately before the combination shall be proportionately increased so that the number of Common Shares issuable on conversion of each Preferred Share shall be decreased in proportion to such decrease in the aggregate number of Common Shares outstanding. Any adjustment under this subsection shall become effective at the close of business on the date the subdivision or combination becomes effective.

3.05 Adjustment for Certain Distributions

In the event the LLC at any time or from time to time after the Series B Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Shares entitled to receive, a distribution payable on the Common Shares in additional Common Shares, then and in each such event the Conversion Price in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Conversion Price then in effect by a fraction: (a) the numerator of which shall be the total number of Common Shares issued and outstanding immediately prior to the time of such issuance or the close of business

on such record date, and (b) the denominator of which shall be the total number of Common Shares issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of Common Shares issuable in payment of such distribution. Notwithstanding the foregoing (i) if such record date shall have been fixed and such distribution is not fully paid or if such distribution is not fully made on the date fixed therefor, the Conversion Price shall be recomputed accordingly as of the close of business on such record date and thereafter the Conversion Price shall be adjusted pursuant to this subsection as of the time of actual payment of such distributions; and (ii) that no such adjustment shall be made if the holders of Preferred Shares simultaneously receive a distribution of Common Shares in a number equal to the number of Common Shares as they would have received if all outstanding Preferred Shares had been converted into Common Shares on the date of such event.

3.06 Adjustment for Merger or Reorganization, etc.

Subject to the provisions of Section 10.04, if there shall occur any reorganization, recapitalization, reclassification, consolidation or merger involving the LLC in which the Common Shares (but not the Preferred Shares) is converted into or exchanged for securities, cash or other property (other than a transaction covered by Sections 3.03 or 3.05), then, following any such reorganization, recapitalization, reclassification, consolidation or merger, each Preferred Share shall thereafter be convertible in lieu of the Common Shares into which it was convertible prior to such event into the kind and amount of securities, cash or other property which a holder of the number of Common Shares of the LLC issuable upon conversion of one Preferred Share immediately prior to such reorganization, recapitalization, reclassification, consolidation or merger would have been entitled to receive pursuant to such transaction; and, in such case, appropriate adjustment (as determined in good faith by the Board) shall be made in the application of the provisions in this Article III with respect to the rights and interests thereafter of the holders of the Preferred Shares, to the end that the provisions set forth in this Article III (including provisions with respect to changes in and other adjustments of the Conversion Price) shall thereafter be applicable, as nearly as reasonably may be, in relation to any securities or other property thereafter deliverable upon the conversion of the Preferred Shares.

3.07 Certificate as to Adjustments

Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to this Article III, the LLC at its expense shall, as promptly as reasonably practicable but in any event not later than 10 days thereafter, compute such adjustment or readjustment in accordance with the terms hereof and furnish to each holder of Preferred Shares a certificate setting forth such adjustment or readjustment (including the kind and amount of securities, cash or other property into which the Preferred Shares is convertible) and showing in detail the facts upon which such adjustment or readjustment is based. The LLC shall, as promptly as reasonably practicable after the written request at any time of any holder of Preferred Shares (but in any event not later than 10 days thereafter), furnish or cause to be furnished to such holder a certificate setting forth (i) the Conversion Price then in effect, and (ii) the number of Common Shares and the amount, if any, of other securities, cash or property which then would be received upon the conversion of such Preferred Shares.

23

3.08 Notice of Record Date

In the event: (a) the LLC shall take a record of the holders of its Common Shares (or other shares or securities at the time issuable upon conversion of the Preferred Shares) for the purpose of entitling or enabling them to receive any distribution, or to receive any right to subscribe for or purchase any shares of any class or any other securities, or to receive any other security; (b) of any capital reorganization of the LLC, any reclassification of the Common Shares, or any Deemed Liquidation Event; or (c) of the voluntary or involuntary dissolution, liquidation or winding-up of the LLC, then, and in each such case, the LLC will send or cause to be sent to the holders of the Preferred Shares a notice specifying, as the case may be, (i) the record date for such distribution or right, and the amount and character of such distribution or right, or (ii) the effective date on which such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up is proposed to take place, and the time, if any is to be fixed, as of which the holders of record of Common Shares (or such other shares or securities at the time issuable upon the conversion of the Preferred Shares) shall be entitled to exchange their Common Shares (or such other shares or securities) for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up, and the amount per share and character of such exchange applicable to the Preferred Shares and the Common Shares. Such notice shall be sent at least 10 days prior to the record date or effective date for the event specified in such notice.

3.10 No Tax Effect on Conversion

Regular meetings of the Board may be held at such time, date and place as the Board may from time to time determine; provided, however, the Board shall meet at least quarterly, unless otherwise determined by the Board. Special meetings of the Board may be called, orally or in writing, by one or more Managers, designating the time, date and place thereof. Managers may participate in meetings of the Board by means of conference telephone or similar communications equipment by means of which all Managers participating in the meeting can hear each other, and participation in a meeting in accordance herewith shall constitute presence in person at such meeting. The LLC shall reimburse the Managers for all reasonable out-of- pocket expenses incurred by them in connection with attendance at all meetings of the Board and any meetings of committees of the Board and the board of directors of each of the LLC’s subsidiaries, including any meetings of committees thereof (including coach fare of domestic flights and a hotel rate with a maximum reimbursement of $700.00 per night, unless otherwise preapproved by the LLC).

A notice or waiver of notice of a meeting of the Board need not specify the purposes of the meeting.

28

4.09 Quorum

At any meeting of the Board, the presence of a majority of the Managers then in office shall constitute a quorum; provided, however, to the extent that any action to be taken by the Board at any meeting requires the express affirmative vote or consent of at least two of the Preferred Managers, the presence of two of such Preferred Managers shall be the necessary quorum for such action. Less than a quorum may adjourn any meeting from time to time and the meeting may be held as adjourned without further notice.

At any meeting of the Board at which a quorum is present, the act of a majority of the Managers present at such meeting shall be the act of the Board unless a larger number is required by law or by this Agreement.

4.11 Action by Written Consent

Any action required or permitted to be taken at any meeting of the Board may be taken without a meeting if a written consent thereto is signed or consented to by electronic transmission by all of the Managers and filed with the records of the meetings of the Board. Such consent shall be treated as a vote of the Board for all purposes.

4.12 Limitation of Liability of Managers

No Manager shall be obligated personally for any debt, obligation or liability of the LLC or of any Member, whether arising in contract, tort or otherwise, solely by reason of being or acting as Manager of the LLC. A Manager, solely in his, her or its capacity as a Manager, shall not be personally liable to the LLC or the Members for monetary damages for breach of fiduciary duty as a Manager, to the fullest extent permitted by applicable law, except for liability (a) for any breach of such Manager’s duty of loyalty to the LLC or the Members, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law or (c) for any transaction from which such Manager derived any improper personal benefit. The LLC renounces, to the fullest extent permitted by law, any interest or expectancy of the LLC in, or in being offered an opportunity to participate in, any Excluded Opportunity. An “Excluded Opportunity” is any matter, transaction or interest that is presented to, or acquired, created or developed by, or which otherwise comes into the possession of, (i) any Manager who is not an employee of the LLC or any of its subsidiaries or (ii) any holder of Preferred Shares or any partner, member, director, stockholder, employee or agent of any such holder, other than someone who is an employee of the LLC or any of its subsidiaries (collectively, “Covered Persons”), unless such matter, transaction or interest is presented to, or acquired, created or developed by, or otherwise comes into the possession of, a Covered Person expressly and solely in such Covered Person’s capacity as a Manager.

29

4.13 No Agency or Authority

No Manager is an agent of the LLC solely by virtue of being a Manager, and unless expressly authorized to do so by the Board after the date hereof, no Manager has the authority to act for or to bind the LLC solely by virtue of being a Manager. Any Manager who takes any action or purports or attempts to bind the LLC in violation of this Section 4.13 shall be solely responsible for any loss and/or expense incurred by the LLC as a result of such unauthorized action, and such Manager shall indemnify and hold harmless the LLC with respect to such loss and/or expense.

4.14 No Liability for Election of Recommended Managers

No Member, nor any Affiliate of any such Member, shall have any liability solely as a result of designating a person for election as a Manager in accordance with the provisions of this Agreement for any act or omission by such designated person in his or her capacity as a Manager, nor shall any Member have any liability solely as a result of voting for any such Manager in accordance with the provisions of this Agreement.

4.15 No “Bad Actor” Designees

(a) Each person with the right to designate or participate in the designation of a Manager as specified above hereby represents and warrants to the LLC that, to such person’s knowledge, none of the “bad actor” disqualifying events described in Rule 506(d)(1)(i)-(viii) promulgated under the Securities Act (each, a “Disqualification Event”), is applicable to such person’s initial designee named above except, if applicable, for a Disqualification Event as to which Rule 506(d)(2)(ii) or (iii) or (d)(3) is applicable. Any Manager designee to whom any Disqualification Event is applicable, except for a Disqualification Event as to which Rule 506(d)(2)(ii) or (iii) or (d)(3) is applicable, is hereinafter referred to as a “Disqualified Designee”. Each person with the right to designate or participate in the designation of a Manager as specified above hereby covenants and agrees not to designate or participate in the designation of any Manager designee who, to such person’s knowledge, is a Disqualified Designee. In the event (i) such person or (ii) to the extent such person referred to in this Section 4.15 is an entity, any general partner or managing member of such entity, or any executive officer of such entity, becomes aware that any individual previously designated by any such person is or has become a Disqualified Designee, such person or the appropriate representative of such entity (as applicable) shall as promptly as practicable take such actions as are necessary to remove such Disqualified Designee from the Board and designate a replacement designee who is not a Disqualified Designee.

(b) Each Member hereby represents and warrants to the LLC that, except as disclosed in writing to the LLC, no Disqualification Event is applicable to such Member. Each Member covenants to provide immediate written notice to the LLC in the event that a Disqualification Event becomes applicable to such Member. Each Member covenants to provide such information to the LLC as the LLC may reasonably request in order to comply with the disclosure obligations set forth in Rule 506(e) promulgated under the Securities Act, as may be amended from time to time.

ARTICLE VI. Indemnification

6.01 Indemnification of Managers and Officers

Except for claims as to which such Manager or officer has expressly agreed in writing to provide indemnity or has otherwise guaranteed any obligation of the LLC or any subsidiary of the LLC, the LLC shall indemnify, to the fullest extent permitted by the Act as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the LLC to provide broader indemnification rights than said law permitted the LLC to provide prior to such amendment) any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (whether or not brought by or in the right of the LLC) by reason of the fact that he or she is or was a Manager or officer of the LLC, or is or was serving at the request of the LLC as a director, manager or officer of another corporation, partnership, limited liability company, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such suit, action or proceeding if he or she acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the LLC, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the LLC and, with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful. Notwithstanding the foregoing, the LLC shall indemnify any such person seeking indemnification in connection with an action, suit or proceeding initiated by such person only if the initiation and continued prosecution of such action, suit or proceeding was authorized by the Board.

32

6.02 Indemnification of Employees and Agents

The Board, in its discretion, may authorize the LLC to indemnify any person who was or is a party or is threatened to be made a party to any threatened pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (whether or not brought by or in the right of the LLC) by reason of the fact that he or she is or was an employee or agent of the LLC, or is or was serving at the request of the LLC as an employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit or proceeding if he or she acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the LLC and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the LLC and, with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful.

6.03 Indemnification Upon Successful Defense

Except for claims as to which such Manager, officer or employee has agreed to provide indemnity or has otherwise guaranteed any obligation of the LLC or any subsidiary of the LLC, notwithstanding the other provisions of this Article VI, to the extent that a Manager, officer or employee of the LLC has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Section 6.01 or 6.02 of this Agreement, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees and disbursements) and costs actually and reasonably incurred by such person in connection therewith.

6.04 Advance Payments

Expenses incurred in defending a civil or criminal action, suit or proceeding may be paid by the LLC in advance of the final disposition of such action, suit or proceeding, only as authorized by the Board in the specific case (including by one or more Managers who may be parties to such action, suit or proceeding), upon receipt of an undertaking by or on behalf of the Manager, officer, employee or agent to repay such amount if it shall ultimately be determined that he or she is not entitled to be indemnified by the LLC as authorized in this Article VI.

33

6.05 Non-Exclusive Nature of Indemnification

The indemnification provided herein shall not be deemed exclusive of any other rights to which any person, whether or not entitled to be indemnified hereunder, may be entitled under any statute, by-law, agreement, vote of Members or Managers or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a Manager, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person. Each person who is or becomes a Manager as aforesaid shall be deemed to have served or to have continued to serve in such capacity in reliance upon the indemnity provided for in this Article VI. The LLC hereby acknowledges that a Manager may have other sources of indemnification or insurance, whether currently in force or established in the future (collectively, the “Outside Indemnitors”). The LLC hereby agrees: (a) that it is the indemnitor of first resort (i.e., its obligations to the Manager are primary and any obligation of the Outside Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by the Manager are secondary); (b) that it shall be required to advance the full amount of expenses incurred by the Manager and shall be liable in full for all indemnifiable amounts to the extent legally permitted and as required hereby or any agreement between the LLC and the Manager, without regard to any rights the Manager may have against the Outside Indemnitors; and (c) that it irrevocably waives, relinquishes and releases the Outside Indemnitors from any and all claims against the Outside Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The LLC further agrees that no advancement or payment by the Outside Indemnitors on behalf of the Manager with respect to any claim for which the Manager have sought indemnification from the LLC shall affect the foregoing and the Outside Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of the Manager against the LLC. If for any reason a court of competent jurisdiction determines that the Outside Indemnitors are not entitled to the subrogation rights described in the preceding sentence, the Outside Indemnitors shall have a right of contribution by the LLC to the Outside Indemnitors with respect to any advance or payment by the Outside Indemnitors to or on behalf of an Indemnified Person. The LLC agrees that the Outside Indemnitors are express third party beneficiaries of the terms hereof.

6.06 Insurance

The LLC may purchase and maintain insurance on behalf of any person who is or was a Manager, officer, employee or agent of the LLC, or is or was serving at the request of the LLC as a director, manager, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the LLC would have the power to indemnify him or her against such liability under the provisions of the Act (as presently in effect or hereafter amended) or this Agreement.

ARTICLE VII. Transactions with Interested Persons

7.01 Transactions with Interested Persons

No contract or transaction between the LLC and one or more of its Managers or Members, or between the LLC and any other corporation, partnership, association or other organization in which one or more of its Managers or Members have a financial interest or are directors, managers, partners, stockholders, members or officers, shall be voidable solely for this reason or solely because said Manager or Member was present at, or participated in, the authorization of such contract or transaction if:

(a) the material facts as to the relationship or interest of said Manager or Member and as to the contract or transaction were disclosed or known to the other Managers (if any) or the Members and the contract or transaction was authorized by the affirmative vote of a majority of the disinterested Managers (if any) even though the disinterested Managers may be less than a quorum or the contract or transaction was authorized by the affirmative vote of a majority of the Voting Shares (determined on an as-converted to Common Shares basis) held by the disinterested Members (if any) even though the disinterested Members may be less than a quorum; or

(b) the contract or transaction was fair to the LLC as of the time it was authorized, approved or ratified by the Board.

No Manager or Member interested in such contract or transaction, because of such interest, shall be considered to be in breach of this Agreement or liable to the LLC, any Manager or Member, or any other person or organization for any loss or expense incurred by reason of such contract or transaction or shall be accountable for any gain or profit realized from such contract or transaction.

ARTICLE VIII. Capital Accounts, Contributions and Loans

8.01 Capital Accounts

A separate capital account (a “Capital Account”) shall be maintained for each Member in accordance with Treasury Regulations Section 1.704-1(b)(2)(iv), and this Section 8.01 shall be interpreted and applied in a manner consistent with said Section of the Treasury Regulations. Each Member’s Capital Account (a) shall be increased by (i) the amount of money contributed by such Member to the LLC, (ii) the fair market value of property contributed by such Member to the LLC (net of liabilities secured by such contributed property that the LLC is considered to assume or take subject to under Code Section 752) and (iii) allocations to such Member of net income and any items of income or gain allocated to such Member pursuant to Article IX and (b) shall be decreased by (i) the amount of money distributed to such Member by the LLC, (ii) the fair market value of property distributed to such Member by the LLC (net of liabilities secured by such distributed property that such Member is considered to assume or take subject to under Code Section 752) and (iii) allocations to such Member of net losses and any items of loss or deduction allocated to such Member pursuant to Article IX. Upon the disposition of any Shares, the Capital Account of the disposing Member that is attributable to such Shares shall carry over to the assignee in accordance with the provisions of Treasury Regulation Section 1.704-1(b)(2)(iv)(1). In accordance with Treasury Regulations Section 1.704-1(b)(2)(iv)(f), the LLC shall adjust the Capital Accounts of its Members to reflect revaluations (including any unrealized income, gain or loss) of the LLC property (including intangible assets such as goodwill), whenever it issues additional interests in the LLC (including any interests with a zero initial Capital Account), whenever it redeems interests in the LLC, whenever the adjustments would otherwise be permitted under such Treasury Regulations or as provided in Section 3.01(b)(vi). In the event that the Capital

35

Accounts of the Members are so adjusted, (1) the Capital Accounts of the Members shall be adjusted in accordance with Treasury Regulations Section 1.704-1(b)(2)(iv)(g) for allocations of depreciation, depletion, amortization and gain or loss, as computed for book purposes, with respect to such property and (2) the amount of upward and/or downward adjustments to the book value of the LLC property shall be treated as net income, net loss, gross income, gain, gross deduction and/or gross loss for purposes of applying the allocation provisions of Article IX.

8.02 Contributions

Each Member has made the contribution to the capital of the LLC (each, a “Contribution”) as set forth in the LLC’s records. The value of all non-cash Contributions made by Members shall be determined by the Board. No Member shall be entitled to any interest or compensation with respect to its Contribution or any services rendered on behalf of the LLC except as specifically provided in this Agreement or approved by the Board. No Member shall have any liability for the repayment of the Contribution of any other Member and each Member shall look only to the assets of the LLC for a return of his, her or its Contribution.

ARTICLE IX. Allocations

9.01 Allocation of Net Income

Subject to Sections 9.04 through 9.17, net income for any fiscal year or portion thereof shall be allocated among the Members as follows:

(a) First, to the Members until the aggregate allocations of net income to such Members pursuant to this Section 9.01(a) are equal to the aggregate allocations of net loss to such Members pursuant to Section 9.02(c), in proportion to such unoffset net losses;

(b) Thereafter, to the Members until the aggregate allocations of net income to such Members pursuant to this Section 9.01(b) are equal to the aggregate allocations of net loss to such Members pursuant to Section 9.02(b), in proportion to such unoffset losses;

(c) Thereafter, to the holders of the Preferred Shares, on a pari passu basis, until the aggregate allocations of net income to such holders pursuant to this Section 9.01(c) are equal to the aggregate allocations of net loss to such holders pursuant to Section 9.02(a) (in proportion to such unoffset net losses) to the extent such allocations of net loss caused the Capital Accounts of such holders to be less than the aggregate Initial Preferred Liquidation Amount (as defined below) in respect of all of the Preferred Shares held by such holders; and

(d) Thereafter, to the Members in proportion to the number of Shares held by such Members (with each Preferred Share treated as the number of Common Shares into which such Preferred Share is then convertible).

36

9.02 Allocation of Net Loss

Subject to Sections 9.03 through 9.17, net loss for any fiscal year or portion thereof shall be allocated among the Members as follows:

(a) First, to the holders of Preferred Shares in proportion of the number of Preferred Shares held by such holders to the extent of their positive Capital Account balances;

(b) Thereafter, to the Members in proportion to the number of Shares held by such Members (with each Preferred Share treated as the number of Common Shares into which such Preferred Share is then convertible) to the extent of their positive Capital Account balances; and

(c) Thereafter, to the Members in proportion to the number of Shares held by such Members (with each Preferred Share treated as the number of Common Shares into which such Preferred Share is then convertible).

9.03 Loss Limitation

Net loss allocated pursuant to Section 9.02 shall not exceed the maximum amount of net loss that can be allocated without causing or increasing a deficit balance in any Member’s Capital Account (in excess of such Member’s obligation to restore a deficit in its Capital Account, including any deemed obligation pursuant to the penultimate sentences of Treasury Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5)). In the event that some but not all of the Members would have deficit balances in their Capital Accounts as a consequence of allocations of net loss pursuant to Section 9.02 in excess of the amount, if any, permitted under the preceding sentence, the limitation set forth in this Section 9.03 shall be applied on a Member by Member basis, and net loss not allocable to any Member as a result of this limitation shall be allocated to the other Members in proportion to the positive balances of such Members’ Capital Accounts so as to allocate the maximum amount of net loss to each Member under Treasury Regulations Section 1.704-1(b)(2)(ii)(d). In making the foregoing determination, a Member’s Capital Account shall be reduced by the amounts described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5), or (6).

9.04 Allocations Upon Conversion

Notwithstanding any other provision of this Article IX (except Sections 9.06 through 9.12), in the year of a conversion of Preferred Shares into Common Shares under Section 3.02 and immediately prior to such conversion, net income (or, if applicable, net loss) shall first be allocated to the holder of Preferred Shares so converting, pro rata in proportion to such Preferred Shares being converted until the Capital Account balance attributable to each such Preferred Share being converted is equal to the aggregate Capital Account balance attributable to all outstanding Common Shares divided by the number of outstanding Common Shares multiplied by the number of Common Shares into which such Preferred Shares are convertible. If net income (or, if applicable, net loss) in any year is insufficient to make the full allocation provided for in the preceding sentence, then, in lieu of such special allocation of net income (or, if applicable, net loss) provided for in the preceding sentence, items of gross income (or, if applicable, gross deductions) shall be allocated to the holders of Preferred Shares being converted and, if such gross items are insufficient to make the full required allocation, items of gross deductions (or, if applicable, gross income) shall be made to the holders of Common Shares pro rata in proportion to such Common Shares outstanding. If (a) in any year gross items are insufficient to make the full allocation provided in this Section 9.04 and (b) the LLC’s federal

37

income tax return for the immediately preceding year has not yet been filed, in each case determined as of the event giving rise to such allocation, then any such shortfall shall be taken into account in such immediately preceding year rather than in the current year as an allocation to be made under this Section 9.04. Immediately after any conversion under Section 3.02, the Capital Account balances of the Preferred Shares being converted shall be allocated to the holders of the Common Shares received upon such a conversion, pro rata in proportion to such Common Shares.

9.05 Allocations Upon Liquidation or Sale

Notwithstanding any other provision of this Article IX (except Sections 9.06 through 9.12), in the year in which the LLC liquidates (within the meaning of Treasury Regulations Section 1.704-1(b)(2)(ii)(g)), or sells all or substantially all of the assets of the LLC, or recapitalizes, net income shall first be allocated to the holders of Shares to eliminate any deficit balance in a Member’s Capital Account and thereafter net income (or net loss) shall be allocated to the Capital Account balances of the Members so as to permit liquidating distributions in accordance with Section 10.04(a). If net income (or, if applicable, net loss) in any year is insufficient to make the full allocation provided for in the preceding sentence, then, in lieu of such special allocation of net income (or, if applicable, net loss) provided for in the preceding sentence, items of gross income (or, if applicable, gross deductions) shall be allocated to the holders of Shares to the extent required to satisfy the preceding sentence. If (a) in any year gross items are insufficient to make the full allocation provided in this Section 9.05 and (b) the LLC’s federal income tax return for the immediately preceding year has not yet been filed, in each case determined as of the event giving rise to such allocation, then any such shortfall shall be taken into account in such immediately preceding year rather than in the current year as an allocation to be made under this Section 9.05.

9.06 Qualified Income Offset

Any Member who unexpectedly receives an adjustment, allocation or distribution described in Treasury Regulations Section l.704- l(b)(2)(ii)(d)(4), (5) or (6) that causes or increases a deficit balance in its Capital Account in excess of any obligation to restore a deficit balance in its Capital Account (including a deemed deficit restoration obligation pursuant to Treasury Regulations Sections 1.704-2(g)(1) and (i)(5), and adjusted as provided in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)) shall be allocated items of income and gain in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations, such deficit balance as quickly as possible. This Section 9.06 is intended to comply with the alternate test for economic effect set forth in Treasury Regulations Section l.704-l(b)(2)(ii)(d) and shall be interpreted and applied in a manner consistent therewith.

9.07 Gross Income Allocation

In the event any Member has a deficit Capital Account at the end of any year which is in excess of the amount such Member is deemed to be obligated to restore pursuant to the penultimate sentences of Treasury Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such Member shall be specially allocated items of LLC income and gain in the amount of such excess as quickly as possible, provided that an allocation pursuant to this Section 9.07 shall be made only if and to the extent that such Member would have a deficit Capital Account in excess of such sum after all other allocations provided for in this Article IX have been made as if Section 9.06 and this Section 9.07 were not in the Agreement.

38

9.08 Nonrecourse Deductions

Nonrecourse Deductions shall be allocated among the Members in accordance with Sections 9.02 and 9.10. For purposes of this Section 9.08, the term “Nonrecourse Deductions” shall have the meaning set forth in Treasury Regulations Section 1.7042(b)(1).

9.09 LLC Minimum Gain Chargeback

Notwithstanding any other provisions of this Article IX, in the event there is a net decrease in LLC Minimum Gain during an LLC fiscal year, the Members shall be allocated items of income and gain in accordance with Treasury Regulations Section 1.704-2(f). For purposes of this Article IX, the term “LLC Minimum Gain” shall have the meaning for “partnership minimum gain” set forth in Treasury Regulations Section 1.704-2(b)(2), and any Member’s share of LLC Minimum Gain shall be determined in accordance with Treasury Regulations Section 1.704-2(g)(1). This Section 9.09 is intended to comply with the minimum gain chargeback requirement of Treasury Regulations Section 1.704-2(f) and shall be interpreted and applied in a manner consistent therewith.

9.10 Member Nonrecourse Debt

Notwithstanding any other provisions of this Article IX, to the extent required by Treasury Regulations Section 1.704-2(i), any items of income, gain, deduction and loss of the LLC that are attributable to a nonrecourse debt of the LLC that constitutes Member Nonrecourse Debt (including chargebacks of “partner nonrecourse debt minimum gain” (as used in the Code) (the “Member Nonrecourse Debt Minimum Gain”)) shall be allocated in accordance with the provisions of Treasury Regulations Section 1.704-2(i). For purposes of this Article IX, the term “Member Nonrecourse Debt” shall have the meaning for “partner nonrecourse debt” set forth in Treasury Regulations Section 1.704-2(b)(4). This Section 9.10 is intended to satisfy the requirements of Treasury Regulations Section 1.704-2(i) (including the partner nonrecourse debt chargeback requirements) and shall be interpreted and applied in a manner consistent therewith.

9.11 Member Minimum Gain Chargeback

Except as otherwise provided in Treasury Regulations Section 1.704-2(i)(4), notwithstanding any other provision of this Article IX, if there is a net decrease in Member Nonrecourse Debt Minimum Gain attributable to a Member Nonrecourse Debt during any fiscal year, each Member who has a share of the Member Nonrecourse Debt Minimum Gain attributable to such Member Nonrecourse Debt, determined in accordance with Treasury Regulations Section 1.704-2(i)(5), shall be specially allocated items of LLC income and gain for such fiscal year (and, if necessary, subsequent fiscal years) in an amount equal to such Member’s share of the net decrease in Member Nonrecourse Debt Minimum Gain attributable to such Member Nonrecourse Debt determined in accordance with Treasury Regulations Section 1.704- 2(i)(4). Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Member pursuant thereto. The items to be so allocated shall be determined in accordance with Treasury Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2). This Section 9.11 is intended to comply with the minimum gain chargeback requirement in Treasury Regulations Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

39

9.12 Curative Allocations

The allocations set forth in Sections 9.06 through 9.11 (the “Regulatory Allocations”) are intended to comply with the requirements of Treasury Regulations Sections 1.704-1(b) and 1.704-2. Notwithstanding any other provisions of this Article IX (other than the Regulatory Allocations), the Regulatory Allocations shall be taken into account in allocating other items of income, gain, deduction and loss among the Members so that, to the extent possible, the net amount of such allocations of other items and the Regulatory Allocations to each Member shall be equal to the net amount that would have been allocated to each such Member if the Regulatory Allocations had not occurred. This Section 9.12 shall be interpreted and applied in such a manner and to such extent as is reasonably necessary to eliminate, as quickly as possible, permanent economic distortions that would otherwise occur as a consequence of the Regulatory Allocations in the absence of this Section 9.12.

9.13 Distributions of Nonrecourse Liability Proceeds

If, during a taxable year, the LLC makes a distribution to any Member that is allocable to the proceeds of any nonrecourse liability of the LLC that is allocable to an increase in LLC Minimum Gain pursuant to Treasury Regulations Section 1.704-2(h), then the LLC shall elect, to the extent permitted by Treasury Regulations Section 1.704-2(h)(3), to treat such distribution as a distribution that is not allocable to an increase in LLC Minimum Gain.

9.14 Allocation of Debt

For tax purposes, the indebtedness of the LLC shall be allocated among the Members under Code Section 752.

9.15 Compliance with Code Section 704(b)

The allocation provisions contained in this Article IX are intended to comply with Code Section 704(b) and the Treasury Regulations promulgated thereunder and shall be interpreted and applied in a manner consistent therewith.

9.16 Section 704(c)

In accordance with Section 704(c) of the Code and the Treasury Regulations promulgated thereunder, property contributed to the LLC, which at the time of contribution has a fair market value as reflected in the Capital Account of the contributing Member in excess of its adjusted tax basis, is treated as Section 704(c) property. Items of income, gain, loss, and deduction with respect to any Section 704(c) property shall solely for Federal income tax purposes be allocated among the Members so as to take into account any variation between the adjusted tax basis of the property contributed to the LLC and its initial fair market value. The method for allocating such items of income, gain, loss, and deduction shall be the “traditional method” described in Treasury Regulation Section 1.704-3(b). In the event the book value of any property of the LLC

40

is adjusted pursuant to this Agreement, allocations of income, gain, loss, and deduction and credit with respect to such property shall take into account any variation between the adjusted price of such property for Federal income tax purposes and its fair market value in the same manner as under Section 704(c) of the Code and the Treasury Regulations promulgated thereunder.

9.17 Forfeiture Allocations

If allocations have been made to a Capital Account of an Incentive Member with respect to the Incentive Member’s Unvested Incentive Shares and any portion of such Unvested Incentive Shares is forfeited or the ownership thereof does not completely vest in accordance with the instrument under which the Unvested Incentive Shares were issued, then the “forfeiture allocations” described in Proposed Treasury Regulations Sections 1.704-1(b)(4)(xii)(c) and 1.704-1(b)(4)(xii)(d), or as otherwise provided in the Proposed Rules, may be made to the Incentive Member’s Capital Account in the manner described therein so that allocations of the LLC’s net income, net loss and separate items thereof have economic effect as required by Section 704(b) of the Code.

9.18 Determinations

For purposes of this Agreement, “net income” and “net losses” shall be determined in a manner that is consistent with Section 703 of the Code and shall be adjusted to the extent necessary to reflect the requirements of Sections 704 and 705 of the Code and the Treasury Regulations promulgated thereunder (including without limitation, the requirements of Section 704(c) and the “substantial economic effect” safe harbor). Any elections or other decisions relating to Capital Accounts and tax allocations shall be made by the LLC in any manner that reasonably reflects the purpose and intent of this Agreement.

ARTICLE X. Distributions

10.01 Distribution of LLC Funds

(a) Subject to Section 2.05, the Members shall be entitled to receive distributions only (x) when determined by the Board, (y) as contemplated by Section 10.03 or (z) as contemplated by Section 10.04 in the event of any voluntary or involuntary liquidation, dissolution or winding up of the LLC or Deemed Liquidation Event. To the extent that the Board determines that any distributions shall be made to the Members other than distributions pursuant to Section 10.03 or 10.04, such distributions shall be distributed to the Members in the following order of priority:

(i) First, to the holders of the Preferred Shares, pro rata in proportion to the aggregate Initial Preferred Liquidation Amounts in respect of all of the Preferred Shares held by such holders until the LLC has made aggregate distributions in respect of such Preferred Shares such that the aggregate unpaid Initial Preferred Liquidation Amount in respect of such Preferred Shares is equal to $0; and

(ii) Thereafter, to the Members in proportion to the number of Shares held by such Members (with each Preferred Share treated as the number of Common Shares into which such Preferred Share is then convertible); provided, however, that any such distributions in respect of Incentive Shares shall be subject to the terms and conditions set forth in Section 10.05.

41

(b) No Member shall be entitled to any distribution or payment with respect to its interest in the LLC except as set forth in this Agreement. Distributions may be limited and repayable as provided in the Act.

10.02 Amount Withheld

The LLC is authorized to withhold from distributions or with respect to allocations and pay over to any federal, state, local or foreign government any amounts required to be withheld with respect to any Member pursuant to any provisions of federal, state, local or foreign law. All amounts so withheld shall be treated as amounts distributed to the Members pursuant to Section 10.01 of this Agreement. To the extent any amount withheld with respect to a Member pursuant to this Section 10.02 for any year exceeds the amount distributable to such Member for such year, such Member shall repay such excess to the LLC within ten (10) days after such Member receives written notice from the LLC of the amount of such excess. The LLC will withhold, from all payments owed to each Member hereunder, United States withholding taxes at the rate provided under Section 10.03(a)(ii)(B) unless the LLC has received from such Member proof, satisfactory to the LLC in its sole discretion, that payment to such Member is exempt from withholding taxes or subject to a reduced treaty rate as documented on a U.S. Treasury Form W- 9, W-8ECI, W-8BEN, or other applicable W-8 as the case may be. Each such Member shall provide such documentation to the LLC within fifteen (15) days after the date of this Agreement or prior to any distribution made to such Member, whichever comes first.

10.03 Tax Distributions

(a) Notwithstanding Section 10.01 hereof, within ten (10) days after March 31, May 31, August 31 and December 31 of each fiscal year (each, a “Tax Quarter”), the Board shall (i) estimate the amount of taxable income of the LLC allocable to each Member (for avoidance of doubt, disregarding all deductions, credits, tax benefits, etc. personal to such Member, including any such items arising pursuant to the operation of Code Section 743) for federal income tax purposes for the period beginning on the first day of the fiscal year through the end of such Tax Quarter and (ii) to the extent that funds are legally available therefor, advance to each Member, other than a tax-exempt Member, an aggregate amount equal to the product of (A) the net taxable income, if any, of the LLC for such Tax Quarter allocable to such Member, times (B) the highest applicable effective marginal Federal and state income tax rate for either an individual or a corporation which is domiciled in the State of California, U.S.A. and assuming all income is allocated to the State of California, U.S.A. All amounts so advanced shall be treated as amounts distributed to the Member pursuant to Section 10.01, and shall be reduced by any amount withheld with respect to the Member pursuant to Section 10.02.

(b) If the LLC does not have funds legally available to distribute on a timely basis the full tax distributions that would otherwise be required pursuant to Section 10.03(a) above, then: (i) such tax distributions shall be made to the Members in proportion to the tax distributions they would receive had the full amount of funds been available; and (ii) the unpaid amount shall carry forward and be paid by the LLC as soon as the LLC has funds legally available.

42

10.04 Distribution Upon Liquidation or Dissolution

(a) In the event the LLC (or a Member’s interest therein) is “liquidated” within the meaning of Treasury Regulations Section 1.704-1(b)(2)(ii)(g), subject to the prior payment of all liabilities of the LLC, subject to Section 10.05 with respect to distributions to Incentive Members, all distributions shall be made pursuant to this Section 10.04 to the Members (or such Member, as appropriate) in accordance with their positive Capital Account balances pursuant to Treasury Regulations Section 1.704-1(b)(2)(ii)(b)(2). The parties to this Agreement intend that the allocation provisions contained in this Agreement shall produce final Capital Account balances of the Members that will permit liquidating distributions to be made to the Members pursuant to Section 10.04(b). To the extent that the allocation provisions contained in this Agreement (including, without limitation, Section 9.05) fail to produce such final adjusted Capital Account balances, (i) such provisions shall be amended if and to the extent necessary to produce such result, (ii) net income and net losses of the LLC (or items of gross income and deduction of the LLC) shall be allocated by the LLC among the Members for current and future years and (iii) the provisions of this sentence shall control notwithstanding any reallocation or adjustment of net income or net loss (or items thereof) by the Internal Revenue Service or other taxing authority. Notwithstanding anything to the contrary herein, if, after any amendments and allocations provided in the immediately preceding sentence, the final Capital Account balances of the Members are still not consistent with the liquidating distributions to be made to the Members pursuant to Section 10.04(b), such liquidating distributions shall be made in accordance with Section 10.04(b) rather than this Section 10.04(a).

(b)

(i) In the event of any voluntary or involuntary liquidation, dissolution or winding up of the LLC, the holders of Preferred Shares then outstanding shall be entitled to be paid out of the assets of the LLC available for distribution to the Members, and in the event of a Deemed Liquidation Event (as defined below) the holders of Preferred Shares then outstanding shall be entitled to be paid out of the consideration payable to the Members in such Deemed Liquidation Event or out of the Available Proceeds (as defined below), as applicable, before any payment shall be made to the holders of Common Shares and Incentive Shares by reason of their ownership thereof, an amount per Preferred Share equal to the difference between (A) the Original Issue Price in respect of such Preferred Share and (B) the amount previously distributed by the LLC in respect of such Preferred Share under Section 10.01(a)(i) (the amount payable pursuant to this sentence, is hereafter referred to as the “Initial Preferred Liquidation Amount”). If upon any such liquidation, dissolution or winding up of the LLC or Deemed Liquidation Event, the assets of the LLC available for distribution to the Members shall be insufficient to pay the holders of Preferred Shares the full amount to which they shall be entitled under this Section 10.04(b)(i), the holders of Preferred Shares shall share ratably in any distribution of the assets available for distribution in proportion to the respective amounts which would otherwise be payable in respect of the Preferred Shares held by them upon such distribution if all amounts payable on or with respect to such Preferred Shares were paid in full.

(ii) In the event of any voluntary or involuntary liquidation, dissolution or winding up of the LLC, after the payment in full of all Initial Preferred Liquidation Amounts required to be paid to the holders of Preferred Shares, the remaining assets of the LLC available for distribution to the Members or, in the case of a Deemed Liquidation Event, the consideration

43

not payable to the holders of Preferred Shares pursuant to Section 10.04(b)(i) or the remaining Available Proceeds, as the case may be, shall be distributed among the holders of Preferred Shares, Common Shares and Incentive Shares, pro rata based on the number of Incentive Shares and Common Shares held by each such holder, treating for this purpose all Preferred Shares as if they had been converted to Common Shares pursuant to the terms of this Agreement immediately prior to such liquidation, dissolution or winding up of the LLC or Deemed Liquidation Event; provided, however, that any such distributions in respect of Incentive Shares shall be subject to the terms and conditions set forth in Section 10.05. The aggregate amount which a holder of a Preferred Share is entitled to receive in respect of such Preferred Share under Section 10.04(b)(i) and Section 10.04(b)(ii) is hereinafter referred to as the “Applicable Liquidation Amount.”

(c) Each of the following events shall be considered a “Deemed Liquidation Event” unless the Required Holders elect otherwise by written notice sent to the LLC at least ten (10) days prior to the effective date of any such event:

(i) a merger or consolidation in which (A) the LLC is a constituent party or (B) a subsidiary of the LLC is a constituent party and the LLC issues Shares pursuant to such merger or consolidation, except any such merger or consolidation involving the LLC or a subsidiary in which the Shares outstanding immediately prior to such merger or consolidation continue to represent, or are converted into or exchanged for equity securities that represent, immediately following such merger or consolidation, a majority, by voting power, of the equity securities of (1) the surviving or resulting company; or (2) if the surviving or resulting company is a wholly owned subsidiary of another company immediately following such merger or consolidation, the parent company of such surviving or resulting company; or

(ii) (A) the sale, lease, transfer, exclusive license or other disposition, in a single transaction or series of related transactions, by the LLC or any subsidiary of the LLC of all or substantially all the assets of the LLC and its subsidiaries taken as a whole or (B) the sale or disposition (whether by merger, consolidation or otherwise, and whether in a single transaction or a series of related transactions) of one or more subsidiaries of the LLC if substantially all of the assets of the LLC and its subsidiaries taken as a whole are held by such subsidiary or subsidiaries, except where such sale, lease, transfer, exclusive license or other disposition is to a wholly owned subsidiary of the LLC.

(d)

(i) The LLC shall not have the power to effect a Deemed Liquidation Event referred to in Section 10.04(c)(i)(A) unless the agreement or plan of merger or consolidation for such transaction (the “Merger Agreement”) provides that the consideration payable to the Members of the LLC in such Deemed Liquidation Event shall be paid to the Members of the LLC in accordance with Section 10.04(b).

(ii) In the event of a Deemed Liquidation Event referred to in Section 10.04(c)(i)(B) or 10.04(c)(ii), if the LLC does not effect a dissolution of the LLC under the Act within ninety (90) days after such Deemed Liquidation Event, then (A) the LLC shall send a written notice to each holder of Preferred Shares no later than the ninetieth (90^th) day after the Deemed Liquidation Event advising such holders of their right (and the requirements to be met to

44

secure such right) pursuant to the terms of the following clause; (B) to require the redemption of such Preferred Shares; and (C) if the Required Holders so request in a written instrument delivered to the LLC not later than one hundred twenty (120) days after such Deemed Liquidation Event, the LLC shall use the consideration received by the LLC for such Deemed Liquidation Event (net of any retained liabilities associated with the assets sold or technology licensed, as determined in good faith by the Board), together with any other assets of the LLC available for distribution to the Members, all to the extent permitted by the Act (the “Available Proceeds”), on the one hundred fiftieth (150^th) day after such Deemed Liquidation Event, to redeem all outstanding Preferred Shares at a price per share for each such Preferred Share equal to the Applicable Liquidation Amount in respect of such Preferred Share. Notwithstanding the foregoing, in the event of a redemption pursuant to the preceding sentence, if the Available Proceeds are not sufficient to redeem all outstanding Preferred Shares, the LLC shall redeem a pro rata portion of each holder’s Preferred Shares to the fullest extent of such Available Proceeds, based on the respective amounts which would otherwise be payable in respect of the Preferred Shares to be redeemed if the Available Proceeds were sufficient to redeem all such Preferred Shares, and shall redeem the remaining Preferred Shares as soon as it may lawfully do so under the Act. Prior to the distribution or redemption provided for in this Section 10.04(d), the LLC shall not expend or dissipate the consideration received for such Deemed Liquidation Event, except to discharge expenses incurred in connection with such Deemed Liquidation Event.

(e) Amount Deemed Paid or Distributed. Subject to Section 10.04(f), the amount deemed paid or distributed to the Members of the LLC upon any Deemed Liquidation Event shall be the cash or the value of the property, rights or securities to be paid or distributed to such holders pursuant to such Deemed Liquidation Event. Subject to Section 10.04(f), the value of such property, rights or securities shall be determined in good faith by the Board of the LLC.

(f) Allocation of Escrow and Contingent Consideration. Notwithstanding Section 10.04(e), in the event of a Deemed Liquidation Event, if any portion of the consideration payable to the LLC or the Members is payable only upon satisfaction of contingencies (whether upon the occurrence of any event, the passage of time or otherwise, including, without limitation, any deferred purchase price payments, installment payments, payments made in respect of any promissory note issued in such transaction, payments from escrow, purchase price adjustment payments or payments in respect of “earnouts” or holdbacks) (collectively, the “Additional Consideration”), the definitive agreements with respect to such Deemed Liquidation Event shall provide that (i) the portion of such consideration that is not Additional Consideration (such portion, the “Initial Consideration”) shall be allocated among the Members in accordance with Section 10.04(b)(i) and Section 10.04(b)(ii) as if the Initial Consideration were the only consideration payable in connection with such Deemed Liquidation Event; and (b) any Additional Consideration which becomes payable upon satisfaction of such contingencies shall be allocated among the Members of the LLC in accordance with after taking into account the previous payment of the Initial Consideration as part of the same transaction.

10.05 Distributions on Account of Unvested Shares; Participation Thresholds

(a) Notwithstanding the provisions set forth in Section 10.01 and Section 10.04, no distribution, other than a distribution made in accordance with Section 10.03, shall be made to an Incentive Member with respect to Unvested Incentive Shares held by such Incentive Member. Any amount that would otherwise be distributed to an Incentive Member pursuant to Section 10.01 but for the application of the preceding sentence shall instead be retained by the LLC and paid to such Member if, as and when the Unvested Incentive Shares to which such retained amount relates vests pursuant to the terms of the applicable Award Agreement and the Incentive Plan; provided that, with approval of the Board, which approval must include the affirmative vote, consent or approval of at least two of the Preferred Managers, the Board shall be authorized to distribute retained amounts on any Unvested Incentive Shares to the holder of such Unvested Incentive Shares at such time or times prior to the vesting of such Incentive Shares and upon such terms and conditions as the Board shall deem advisable, and which determination shall be made on an individual by individual basis and need not be uniform among all Incentive Members. If any Unvested Incentive Share ceases to vest or is cancelled, forfeited, repurchased or otherwise acquired by the LLC prior to vesting, all amounts retained by the LLC pursuant to this Section 10.05(a) on account of such Unvested Incentive Share shall be distributed among the holders of the remaining outstanding Shares pursuant to Section 10.01.

(b) Notwithstanding the provisions set forth in Section 10.01 and Section 10.04, no amount shall be distributed with respect to any particular Incentive Share under Section 10.01 or Section 10.04 unless and until the cumulative amount that would be (or has been) distributed to all Shares pursuant to Section 10.01 and Section 10.04 subsequent to the issuance of such Incentive Share exceeds the amount of such Incentive Share’s Participation Threshold and, until such time, the distributions under Section 10.01 and Section 10.04 shall not take into account such Incentive Share (and such amount will be distributed to all other holders of Shares as if such Incentive Share were not outstanding).

ARTICLE XI. Transfer of Shares

11.01 Transfers by Members

(a) Notice of Transfer. Subject to Section 11.02 below, if any Member (the “Transferring Member”) proposes to directly sell, assign, exchange, convey, gift, transfer by bequest, devise or otherwise transfer in any manner (a “Transfer”) all or any portion of his, her or its Shares (the “Transfer Securities”), then the Transferring Member shall promptly give written notice (the “Notice”), simultaneously to the LLC and to each of the Preferred Members. The Notice shall describe in reasonable detail the proposed Transfer including, without limitation, the number and type of Transfer Securities, the nature of such Transfer, the consideration to be paid, the proposed date of consummation of such Transfer and the name and address of each prospective purchaser or transferee and shall be accompanied by copies of all material proposed agreements relating to such proposed Transfer. In the event that the Transfer is being made pursuant to the provisions of Section 11.02, the Notice shall state under which provision the Transfer is being made. No Transfer of Incentive Shares shall be permitted unless such Transfer is approved by the Board. Any Transfer of Shares in violation of this Article XI shall be deemed invalid, null and void, and of no force or effect.

46

(b) Right of First Refusal. Except for Transfers permitted by Section 11.02, with respect to any proposed Transfer by the Transferring Member of Transfer Securities, the LLC shall have the right, exercisable upon written notice to the Transferring Member within ten (10) days after the receipt of the Notice, to purchase all or any portion of the Transfer Securities subject to the Notice on the same terms (including the price) and conditions as set forth therein. The LLC’s purchase right shall be exercised by written notice signed by an officer of the LLC authorized by the Board and delivered to the Transferring Member proposing to Transfer the Transfer Securities and to each of the other Preferred Members. The LLC shall effect the purchase of such Transfer Securities, including payment of the purchase price, within sixty (60) days after (i) if such Transfer Securities are certificated, such date that the Transferring Member shall deliver to the LLC the certificate(s) (if any) representing the Transfer Securities to be purchased by the LLC, each certificate to be properly endorsed for transfer or (ii) if such Transfer Securities are not certificated, such date of LLC’s delivery of exercise notice to the applicable Transferring Member. The Transfer Securities so purchased shall thereupon be cancelled and cease to be issued and outstanding.

(c) Right of Second Refusal.

(i) In the event that the LLC does not elect to purchase all of the Transfer Securities available pursuant to it under Section 11.01(b) within the period set forth therein, the Transferring Member shall give a written notice to the Preferred Members (the “Second Notice”) that shall set forth the Transfer Securities not purchased by the LLC and that shall include the terms of the Notice set forth in Section 11.01(a). For a period of ten (10) days beginning upon the receipt of the Second Notice, the Preferred Members shall have the right to purchase their pro rata share (as determined pursuant to Section 11.01(c)(ii)) of the Transfer Securities subject to the Second Notice on the same terms (including the price) and conditions as set forth therein.

(ii) The pro rata share of each Preferred Member shall be equal to the product obtained by multiplying (x) the aggregate number of Transfer Securities covered by the Second Notice and (y) a fraction, the numerator of which is the number of Shares held by such Preferred Member at the time of the Transfer, calculated on an as-converted to Common Share basis, and the denominator of which is the total number of Shares held by all of such Preferred Members at the time of the Transfer, calculated on an as-converted to Common Share basis.

(iii) In the event that not all of the Preferred Members elect to purchase their full pro rata share (as determined pursuant to Section 11.01(c)(ii)) of the Transfer Securities available pursuant to their rights under Section 11.01(c)(i) within the time period set forth therein, then the Transferring Member shall promptly give written notice (the “Oversubscription Notice”) to each of the Preferred Members who has so elected to exercise its full pro rata share of the Transfer Securities available pursuant to their rights under Section 11.01(c)(i) (the “Participating Members”) which Oversubscription Notice shall set forth the Transfer Securities not purchased by the Preferred Members, and shall offer such Participating Members the right to acquire such unsubscribed Transfer Securities. Each Participating Member shall have ten (10) days after receipt of the Oversubscription Notice (the “Oversubscription Period”) to notify the Transferring Member of its election to purchase all or any portion of the unsubscribed Transfer Securities on the same terms and conditions as set forth in the Second Notice. If the Participating Members elect to

47

purchase more than the total number of unsubscribed Transfer Securities available for purchase, the number of unsubscribed Transfer Securities to be purchased by each Participating Member shall be proportionately reduced based on such Participating Member’s pro rata share of the unsubscribed Transfer Securities. Each Participating Members’ pro rata share for purposes of the immediately preceding sentence shall be equal to the product obtained by multiplying (x) the aggregate number of unsubscribed Transfer Securities covered by the Oversubscription Notice and (y) a fraction, the numerator of which is the number of Shares owned by such Participating Member at the time of the Transfer, calculated on an as-converted to Common Share basis, and the denominator of which is the total number of Shares owned by all of the Participating Members at the time of the Transfer, calculated on an as-converted to Common Share basis. The Participating Members (including the Participating Members who elect to oversubscribe in accordance with this Section 11.01(c)(iii)) shall effect the purchase of the Transfer Securities, including payment of the purchase price, within sixty (60) days after (i) if the Transfer Securities are certificated, such date that the Transferring Member shall deliver to the appropriate Participating Member the certificate(s) (if any) representing the Transfer Securities to be purchased by the Participating Members, each certificate to be properly endorsed for transfer or (ii) if the Transfer Securities are not certificated, the applicable expiration date of such Participating Member’s Oversubscription Period.

(d) Sale of Unpurchased Securities.

(i) If the LLC and/or the Preferred Members elect to purchase all of the Transfer Securities that are the subject of the Notice and/or the Second Notice, the Transferring Member shall honor their elections to purchase and consummate the sale or sales of the Transfer Securities on terms set forth in the Notice and/or the Second Notice, as applicable. If the LLC and/or the Preferred Members do not elect to purchase all of the Transfer Securities that are the subject of the Notice and/or the Second Notice or if they elect to purchase all of such Transfer Securities, but such purchases are not consummated at the closings scheduled therefor (such Transfer Securities not so purchased being the “Unpurchased Securities”), then the Transferring Member shall be entitled to sell all of such Unpurchased Securities to the proposed third party purchaser pursuant to the terms set forth in the Notice and/or the Second Notice, as applicable, subject to the provisions of Section 11.01(e). Any proposed Transfer to a third party purchaser that is not consummated within sixty (60) days after the later of the expiration of the latest-to-expire ten-day period specified in Section 11.01(c)(i) or (iii), as the case may be, and the ten-day period specified in Section 11.01(e)(i), or any proposed Transfer on terms and conditions more favorable to the proposed transferee than those described in the Notice shall again be subject to the rights of the LLC and the Preferred Members in Section 11.01(b) and Section 11.01(c) (the “Refusal Rights”) and, if applicable, the rights of the Preferred Members in Section 11.01(e) (the “Co-Sale Rights”).

(ii) If all or part of the purchase price as stated in the Notice consists of consideration other than cash, then the LLC and the Participating Members shall have the right to purchase the Transfer Securities for cash consideration equal to the sum of the cash consideration, if any, specified in such Notice, plus the fair market value of the non-cash consideration as determined in good faith by the Board.

48

(e) Right of Co-Sale.

(i) In the event that the LLC and/or the Participating Members do not elect to purchase all of the Transfer Securities pursuant to Sections 11.01(b) and Section 11.01(c), the Transferring Member shall deliver to the LLC and each Preferred Member written notice (the “Co-Sale Notice”) that each Preferred Member shall have the right, exercisable upon written notice (the “Co-Sale Response”) to the Transferring Member within ten (10) days after receipt of the Co- Sale Notice, to participate in such Transfer of the Transfer Securities on the same terms and conditions. Such Co-Sale Response shall indicate the number of Shares such holder desires to sell under such holder’s right to participate. To the extent one or more of the Preferred Members exercise such right of participation in accordance with the terms and conditions set forth below, the number of Transfer Securities that the Transferring Member may sell in the transaction shall be correspondingly reduced.

(ii) Each Preferred Member may sell all or any part of its Shares equal to the product obtained by multiplying (A) the aggregate number of Transfer Securities covered by the Co-Sale Notice by (B) a fraction the numerator of which is the number of Shares owned by such Preferred Member at the time of the Transfer, calculated on an as-converted to Common Share basis, and the denominator of which is the sum of (1) the number of Common Shares owned by the Transferring Member, calculated on an as-converted to Common Share basis, and (2) the number of Shares owned by all of the electing Preferred Members at the time of the Transfer, calculated on an as-converted to Common Share basis.

(iii) Each Preferred Member who elects to participate in the Transfer pursuant to this Section 11.01(e) shall effect its participation in the Transfer by promptly delivering in escrow to the LLC for transfer on behalf of such holder to the prospective purchaser one or more certificates (if any), properly endorsed for transfer, which represent the number of Shares that such holder elects to sell; provided, however, that if the Shares are not certificated, then each holder shall effect its participation by delivering written notice to the LLC and the Transferring Member.

(iv) The certificate or certificates (if any) that the Preferred Member delivers to the LLC pursuant to Section 11.01(e)(iii) shall be transferred to the prospective purchaser on consummation of the sale of Transfer Securities pursuant to the terms and conditions specified in the Co-Sale Notice, and the LLC shall concurrently therewith remit to such Preferred Member that portion of the sale proceeds to which such Preferred Member is entitled by reason of its participation in such sale. To the extent that any prospective purchaser or purchasers prohibits such assignment or otherwise refuses to purchase Shares or other securities from another Preferred Member exercising its Co-Sale Rights hereunder, the Transferring Member shall not sell to such prospective purchaser or purchasers any Transfer Securities unless and until, simultaneously with such sale, such Transferring Member shall purchase such Shares or other securities from such Preferred Member on the same terms and conditions specified in the Co-Sale Notice.

(v) The exercise or non-exercise of the rights of the Preferred Members hereunder to participate in one or more Transfers of Transfer Securities made by the Transferring Member shall not adversely affect their rights to participate in subsequent Transfers of Shares.

49

(vi) If none of the Preferred Members elects to participate in the sale of Transfer Securities subject to the Co-Sale Notice, the Transferring Member may, not later than thirty (30) days following delivery to the LLC of the Co-Sale Notice, enter into an agreement providing for the closing of the Transfer of the Transfer Securities covered by the Co-Sale Notice within ten (10) days of such agreement on terms (including the price) and conditions not more favorable to the transferor than those described in the Co-Sale Notice. Any proposed Transfer on terms and conditions more favorable to the proposed transferor than those described in the Co- Sale Notice, as well as any subsequent proposed Transfer of any Shares by the Transferring Member, shall again be subject to the Co-Sale Rights of the Preferred Members and shall require compliance by the Transferring Member with the procedures described in this Section 11.01(e).

(vii) Any participating Preferred Member may withdraw from exercising such participating Preferred Member’s right of co-sale under this Section 11.01(e) in connection with a proposed Transfer at any time prior to the consummation of such Transfer, in which case the number of Transfer Securities that the Transferring Member may sell in the proposed Transfer shall be correspondingly increased to give effect to the non-participation of such Preferred Member.

(viii) Subject to Section 11.01(e)(ix), the aggregate consideration payable to the participating Preferred Members and the Transferring Member shall be allocated based on the number of Transfer Securities sold to the prospective transferee by each participating Preferred Member and the Transferring Member.

(ix) In the event that the proposed Transfer constitutes a Deemed Liquidation Event, the terms of the agreement related to such Transfer shall provide that the aggregate consideration from such Transfer shall be allocated to the participating Preferred Members in accordance with Section 10.04(b).

(f) Termination. The rights and obligations set forth in this Section 11.01 shall not apply in connection with, and shall immediately terminate upon, the earlier of the date of the closing of (i) any sale of Transfer Securities to the public in an offering pursuant to an effective registration statement under the Securities Act (a “Public Offering”) or (ii) a Deemed Liquidation Event.

11.02 Transfers Generally; Permitted Transfers and Prohibited Transferees

(a) Transfers Generally. Subject to compliance with this Agreement and applicable law, Shares may be transferred on the books of the LLC by the surrender to the LLC or its transfer agent of the certificate therefor (if a certificate has been issued in respect thereof) properly endorsed or accompanied by a written assignment or power of attorney properly executed or, in the case of uncertificated Shares, a written assignment or power of attorney properly executed, in each case, with transfer stamps (if necessary) affixed, and with such proof of the authenticity of signature as the LLC or its transfer agent may reasonably require. Prior to any proposed Transfer of Shares (other than pursuant to an effective registration statement in accordance with the Securities Act), the holder thereof shall give written notice to the LLC of its intention to effect such Transfer. Each such notice shall describe the manner of the proposed Transfer and, if requested by the LLC, shall be accompanied by an opinion of counsel reasonably

50

satisfactory to the LLC to the effect that the proposed Transfer may be effected without registration under the Securities Act and any applicable state securities laws, whereupon, subject to compliance with the other terms and conditions set forth in this Agreement, the holder of such Shares shall be entitled to Transfer such Shares in accordance with the terms of its notice; provided, however, that no such opinion of counsel shall be required for a Transfer in connection with a Sale of the LLC. Each certificate (if any) representing Shares Transferred as above provided shall bear the legends set forth in Section 3.12, except that such certificate shall not bear such legend if (i) such Transfer is in accordance with the provisions of Rule 144 (or any other rule permitting public sale without registration under the Securities Act) or (ii) the opinion of counsel referred to above is to the further effect that the transferee and any subsequent transferee (other than an Affiliate of the LLC) would be entitled to Transfer such Shares in a public sale without registration under the Securities Act. Notwithstanding anything to the contrary herein, the LLC shall not recognize any Transfer if, in the opinion of counsel to the LLC, such Transfer would result in the LLC being considered a “publicly traded partnership” under Section 7704 of the Code or would otherwise result in the LLC being classified for federal income tax purposes as an association taxable as a corporation.

(b) Permitted Transfers. Notwithstanding the foregoing, the Refusal Rights and the Co-Sale Rights in Section 11.01 shall not apply to (a) any Transfer by a Member to any parent, spouse, descendant (whether natural or adopted) or sibling of, or trust or other vehicle formed solely for the benefit of and controlled by, such Member and/or any one or more of them or any Affiliate, partner, member, stockholder or other equity holder of such Member, (b) any pledge of Shares made by a Member pursuant to a bona fide loan transaction that creates a mere security interest, (c) any bona fide gift by a Member, (d) any repurchase of Shares from a Member by the LLC or (e) any Transfer by a Preferred Member to (i) any of such Preferred Member’s officers, directors, partners, members or other equity owners, or retired partners, retired members or other retired equity owners, or to the estate of any of such Preferred Member’s partners, members or other equity owners or retired partners, retired members or other retired equity owners or (ii) any venture capital fund, private investment vehicle or similar entity that is controlled by or under common control with one or more general partners, managers, or ultimate beneficial owner, or managing members of, or shares the same management company with, such Preferred Member; provided that the transferee shall furnish the LLC and such holders with a written agreement to be bound by and comply with all provisions of this Agreement; and, provided, further, in the case of any Transfer pursuant to clause (a) or (c) above, that such Transfer is made pursuant to a transaction in which there is no consideration actually paid for such Transfer. Notwithstanding anything to the contrary herein, the provisions of Section 11.01 shall not apply to the sale of any Shares to the public in a Public Offering.

(c) Prohibited Transferees. Notwithstanding the foregoing, no Member shall transfer any Transfer Securities to (i) any entity which, in the determination of the Board, directly or indirectly competes with the LLC or any of its subsidiaries; or (ii) any customer, distributor or supplier of the LLC, if the Board should determine that such transfer would result in such customer, distributor or supplier receiving information that would place the LLC or its subsidiaries at a competitive disadvantage with respect to such customer, distributor or supplier. It being agreed that none of Canaan, Atlas, Access, RA Capital, Viking Global Opportunities Illiquid Investments Sub-Master LP, Janus Henderson Global Life Sciences Fund and Janus Henderson Capital Funds Plc-Janus Henderson Global Life Sciences Fund, Perceptive Life Sciences Master Fund, Ltd., Franklin Strategic Series – Franklin Biotechnology Discovery Fund, Boxer Capital, LLC, or MVA Investors, LLC shall be deemed to directly or indirectly compete with the LLC or any of its subsidiaries.
